Research Interests
Our lab studies the relationship of neural systems to decision-making by using a combination of computational and functional imaging techniques. The approach is called Neuroeconomics. We are particularly interested in the role of the basal ganglia in processing novelty and reward and how this region guides decision-making. Current studies are focused on risky decision making and the neural effects of social messages, the neurobiology of adolescent risk-taking, and neurobiological mechanisms of political conflict.
We use functional imaging techniques, such as fMRI, to probe the function of specific cortico-striatal circuits that we think are involved in motivation. By designing behavioral tasks that manipulate the relative novelty and uncertainty of the information being presented, we are able to probe these circuits in a targeted manner. By using subtle manipulations in the behavioral task, subjects are frequently unaware of their presence, and we are able to measure subconscious brain processes. The circuits that respond to subconscious information changes are also those circuits most commonly implicated in mood and substance use disorders.
